This AD applies to Rolls-Royce plc RB211 Trent 768-60, 772-60, 772B-60, and 772C-60 turbofan engines. These engines are installed on, but not limited to, Airbus A330 series airplanes.
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) provided by the aviation authority for the United Kingdom to identify and correct an unsafe condition on an aviation product. The MCAI states the following:
Inspect the IP compressor drum stage 2-3 interstage spacer for cracking at every shop visit as follows:
(1) If the IP Compressor rotor is not removed from the IP Compressor Casing, inspect the IP compressor drum stage 2-3 interstage spacer by borescope in accordance with Rolls-Royce RB211 Propulsion System Alert Non Modification Service Bulletin RB211-72-AE753 revision 1, section 3 Accomplishment Instructions (paragraphs F and G are applicable in revision 1).
(2) If the IP Compressor rotor is removed from the IP Compressor Casing inspect the IP compressor drum stage 2-3 interstage spacer by Eddy Current Inspection in accordance with Rolls-Royce RB211 propulsion System Alert Non Modification Service Bulletin RB211-72-AF197 initial issue, section 3 accomplishment Instructions.
(3) IP compressor drums on which cracking is identified by the above means must be rejected from service.
None.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
